Hi,
I have set up postfix with a mail_transport to Zarafa. To fix an '
Recipient address rejected: User unknown in local recipient table'
error I have to put an empty 'local_recipient_maps =' in postfix's
main.cf. I do wonder about the security implications of setting this
option. If I understand the documentation correctly it isn't wise to
set this option to empty. Is this correct? Besides the information
below I can't find much information about this option.Thanks in
advance!
Documentation
To turn off unknown local recipient rejects by the SMTP server, specify:
/etc/postfix/main.cf:
local_recipient_maps =
That is, an empty value. With this setting, the Postfix SMTP server
will not reject mail with "User unknown in local recipient table".
Don't do this on systems that receive mail directly from the Internet.
With today's worms and viruses, Postfix will become a backscatter
source: it accepts mail for non-existent recipients and then tries to
return that mail as "undeliverable" to the often forged sender
address.
